Specification of Letters Patent.

Application filed May 7, 1910. Serial No. 559,920.

To all whom it may concern:

Be it known that I, CLAYTON T. VVHIPPLE, a citizen of the United States,residing at Glens Falls, in the county of l/Varren and State of NewYork, have invented certain new and useful Improvements in TubularLantern-Frames, of which the following is aspecification.

This invention relates to that class of lanterns having side tubesleading from the dome to the burner, and has for its object to reducethe number of parts or blanks necessary to construct the lantern; alsoto reduce the number of ressing or forming operations, and the labor ofassembling the parts into the complete article, avoiding also the use ofsoldered joints.

It is old in the art to press or draw the dome or lantern top and toconnect the tubes thereto, as well as to a burner collar, the tubesbeing formed in separate pieces or halves, and the burner collar in aseparate piece or ring. By my invention the whole frame, dome, tubes andburner collar are made in two halves or pieces of sheet metal cut anddrawn to the desired shape. In the preferred form the halves are dividedon the plan across the tubes. As a modification, the dome may be madeseparate from the tubes and seamed on the same plane as the tubes, or ona transverse plane. Or as a further modification the dome may be mademaking the frame in halves and seaming integral with a portion of thetubes. By the same together the cost of construction is materiallyreduced and a stronger and better frame is produced.

The invention is illustrated in the accompanying drawings in whichFigure 1 is a plan view showing one of the blanks or halves, with thedome and burner collar sections integral with the tube sections. Fig. 2is a section such as would appear on the line 2-2 of Fig. 1, if twohalves such as are shown in Fig. 1 were assembled. Fig. 3 is a similarsection of a modification wherein the dome is made separately and seamedon a transverse axis. Fig. 4 is a detail partly in section showing thedome made in separate nieces with the tube sections joined thereto. Fig.5 is a similar detail showing the dome section integral with the upperelbow or part of the air tube.

In the invention as shown in Figs. 1 and 2 the dome 6, with its cap 7,the air tubes 8,

ll 1 I l l I made in separate I l I l and the burner collar 9, are madein halves cut and drawn from a sheet metal blank of proper size, andafter being drawn or pressed to shape these parts are united by lapseaming as shown at 10 in Fig. 2, thereby pro ducing the completelantern frame which will be assembled with the font and other parts,thereby avoiding the labor and expense of producing and assembling theva rious parts separately, as heretofore. One blank or half is cutslightly wider than the other in order that its edges may be lapped overthe edge of the other section when they are assembled.

In the modification shown in Fig. 3 the two halves or parts of the domeare joined on a plane transverse to that of the tubes, and in thisinstance the dome sections are pieces from the tubes, the latter beingjoined thereto as indicated in Fig. 4 or in any other suitable manner.It is within the scope of my invention to form the lamp dome and its capof sectional blanks seamed together, and domes or tops so produced maybe used on tubular lanterns or other lanterns of any kind.

In the modification shown in Fig. 4 the dome sections and cap are madein separate halves and the tubes are seamed at their ends thereto, asshown at 11. Or as shown in Fig. 5 the upper elbows or parts of the airtubes are made integral with the dome sections and joined by a beadedjoint 12 or otherwise to the remaining portion of the tubes. In any ofthe constructions indicated considerable economy of production results,as compared to a top drawn in single con tinuous circular pieces such asthe body and cap which must then be assembled.

What I claim as new is 1. A top blank for a tubular lantern, said blankbeing made of one piece of sheet metal shaped to form side tube portionsand an enlarged integral dome portion between the same, extending bothabove and below the junction of said tube portions therewith.

2. Al tubular lantern frame comprising two similar sheet metal blanks,each blank having side tube portions, an enlarged dome portionconnecting the upper ends of the tube portions, and a burner collarportion connecting the lower ends of the tube portions, said blanksbeing seamed together and forming a dome, side tubes and humor collar.

3. A tubular lantern frame consisting of tWo similar sheet metal blanksconnected totogether at their edges the cap being spaced gether at theiredges, each blank having from the dome. 10 burner collar air tube anddome portions, In testimony whereof, I aflix my signature being enlargedand open in presence of two Witnesses.
